Referencing a Word document that is already open

[heedaf]

To keep this question simple (or so I thought) the word document would already be open since another script will open the document. The following code seems to work but I'm not sure why "Set oRng = objWord.Sections(1).Range" works with getobject but "Set oRng = objWord.activedocument.content" does not.

Private Sub Command0_Click() 
    Dim objWord As Object 
    Dim oRng As Word.Range 
     
    Set objWord = GetObject(, "Word.Application") 
    Set objWord = GetObject("C:/temp/test1.docm") 
     
    Set oRng = objWord.Sections(1).Range 
    Debug.Print oRng.Text 
End Sub
